Improvement in cutters for nail-cutting machines

IMPROVEMENT IN CUTTERS FOR NAIL-CUTTING MACHINES.

Specification forming part of Letters Patent No. 1l 0,6211, datedJanuary 3, 1871.

I, ELEAZR BLEss, of Indianapolis, in the county of Marion and State ofIndiana, have f invented certain Improvements in the Process ofManufacturing Nails, of which the follow.

ing is a specification:

My invention relates to forming or making nails with a sharp orpyramidal point and it consists in the form and arrangement of themovable knife or cutter and the stationary knife or anvil to besubstituted for these parts in the ordinary nail-machines, the object ofthe invention being to manufacture sharppointed nails with greaterexpedition and cheaper than heretofore.

K Description of the Accompanying Drawing.

Figure l is a side elevation of a stationary knife or anvil and amovable knife or cutter, together with a nailplate prepared with sharpor beveled edges, as required to embody and carry out the objects of myinvention, said anvil and cutter being adapted and applied to theordinary nailmachines in the usual manner. Fig. 2 is a top or plan viewof the same. Fig. 3 is an end view of the anvil, together with thenailplate shown thereon in position for cutting nails.

General Description.

A is the stationary knife or anvil, and B the movable knife or cutter,both of which are so formed and arranged that the point end of thenail-blank is tapered on two sides as it is cut from the nail-plate O.

In order to form the nail with a sharp pyramidal point by means of themovable knife and anvil as formed and arranged by me, it is necessary toprepare the nail-plate C with sharp or beveled edges, as shown, as thisforms the taper to the point on the other two sides.

In order to preserve the central position of the point and to keep itfrom being bent by the knife B in the act of cutting the nail-blank fromthe plate, I make the anvilA With raised beveled sides, the elevation ofthe sides being half the thickness of the nailplate C, and so formed asto support the extreme outer edges ofthe plate, as clearly shown in thedrawing.

The form and arrangement of the cutter and anvil are also such as toform the head end of the nail-blank with the sideprojecting parts yleftor made on the sides thereof asa necessary effect of cutting the point,as described, and it so happens that the form thus given to the head endof the blank is such that the head of the nail is formed rounder by theheading-tool and with smoother margins than with the ordinary blank.

The application of my improved cutter and anvil requires no alterationin the ordinary nailcutting machine,.and the nailplate is manipulated asin other machinesthat is, the plate is turned over reversed each time ablau k is out. I

I make no claim to a pointed nail nor to preparing the plate withbeveled or sharp edges, in itself considered, but in the manner orprocess of making sharp-pointed nails.

I claim as my invention- The anvil A and cutter B, formed and arrangedsubstantially as and for the purpose set forth.
